Detailed ways

In order to make the technical problems, technical solutions, and advantages to be solved by the embodiments of the present disclosure clearer, the following describes in detail with reference to the accompanying drawings and specific embodiments.

In the manufacturing process of the related flexible display panel, the flexible display substrate 1 is attached to the flexible film 3 through the adhesive 2. The flexible film 3 provides a certain strength to the flexible display substrate 1. Because the flexible display panel has a bending area, in order to reduce the stress on the wiring in the bending area when the flexible display panel is bent, the related art thinns the flexible film 3 corresponding to the bending area by means of laser cutting. Thickness of the part. When laser cutting is performed, in order to avoid the flexible display panel being damaged due to the laser heating shrinkage of the adhesive 2, the portion of the flexible film 3 corresponding to the bending area will not be completely removed, but the flexible film 3 will be retained. The thickness of the part is about 5um, as shown in Figure 1. Since the portion of the flexible film 3 corresponding to the bending area is not completely removed, when the flexible display panel is bent, the portion of the laminating adhesive 2 corresponding to the bending area will be subject to the flexible display substrate 1 and the flexible film 3 extrusion. Since the adhesive 2 has a certain fluidity, as shown in FIG. 2, wrinkles will be formed at the break of the flexible film 3 (that is, the position where the thickness of the flexible film 2 changes), resulting in a part of the flexible display panel. The risk of line breakage increases, which in turn causes poor display.

In view of the above problems, the present disclosure provides a flexible display panel, a manufacturing method of the flexible display panel, and a display device, which can improve the reliability of bending of the flexible display panel.

Some embodiments of the present disclosure provide a method for manufacturing a flexible display panel. The method includes the following steps S14-S17.

S14: providing a flexible film 3 and a flexible display substrate 1, the flexible film 3 including a first region B and a second region E except the first region B;

S15: forming a laminating adhesive 2 on the second region E of the flexible membrane 3;

S16: The flexible display substrate 1 is bonded to the flexible film 3 through the bonding adhesive 2, wherein the first region B corresponds to the bent region A of the flexible display panel;

S17: Cutting the flexible membrane 3 to remove at least a part of the first region B.

The flexible display panel 100 includes a bending area A and a non-bending area C. The first area B is an area without a glue. The symmetry line of the first area B is consistent with the symmetry line of the bending area A. The area of the first area B may be equal to the area of the bending area A. That is, when the flexible display panel is not bent, the orthographic projection of the bending area A of the flexible display substrate 1 on the flexible film 3 coincides with the first area B. As shown in Figure 3B. The area of the first area B may also be slightly larger than the area of the bending area A. That is, when the flexible display panel is not bent, the orthographic projection of the bending area A of the flexible display substrate 1 on the flexible film 3 falls into the first area B. Inside, as shown in Figure 3A. The area of the first region B can also be slightly smaller than the area of the bent region A, that is, when the flexible display panel is not bent, the orthographic projection of the first region B on the flexible display substrate 1 falls into the bent region A, as shown in FIG. 3C As shown.

Since there is no adhesive or a part of adhesive at the position corresponding to the bending area of the flexible display substrate, when the flexible display panel is bent, the wrinkles of the bending area caused by the flow of the adhesive 2 can be effectively eliminated, and the wrinkle can be reduced. The routing of the flexible display panel creates a risk of breakage, which improves the reliability of the flexible display panel and the durability of the product.

Further, before the step S14 of providing the flexible film 3 and the flexible display substrate 1, the method further includes steps S11-S13.

S11: Provide a rigid carrier board 1000;

S12: forming a flexible display substrate 1 on the rigid carrier board 1000;

S13: The flexible display substrate 1 is peeled from the rigid carrier board 1000.

Since a carrier is required for the preparation of the flexible display substrate 1, it is necessary to first prepare the flexible display substrate 1 on the rigid carrier 1000, and then peel the flexible display substrate 1 from the rigid carrier 1000, and then attach the flexible display substrate 1.

Optionally, the orthographic projection of the bending area A of the flexible display substrate 1 on the flexible film 3 is located in the first area B, as shown in FIG. 3A; or the bending of the flexible display substrate 1 The orthographic projection of the region A on the flexible diaphragm 3 coincides with the first region B. That is, there is no adhesive glue at the position corresponding to the bending area A. Therefore, when the flexible display panel is bent, the pressing of the adhesive glue 2 by the bending between the flexible display substrate 1 and the flexible film 3 can be effectively eliminated. The force causes wrinkles in the bending area caused by the flow of the adhesive 2, reduces the risk of breakage of the flexible display panel wiring, and improves the reliability of the flexible display panel and the durability of the product.

Optionally, the region without the adhesive (ie, the first region B) is slightly larger than the bending region A, and the distance D between the boundary line of the bending region A and the boundary line of the first region B may be 20-30um. In this way, when the flexible display panel is bent, the influence of the adhesive 2 on the bending of the flexible display panel can be completely avoided, and the pressing force on the adhesive 2 due to the bending between the flexible display substrate 1 and the flexible film 3 is eliminated. This leads to wrinkles in the bending area caused by the flow of the adhesive 2, reduces the risk of breakage of the flexible display panel, and improves the reliability of the flexible display panel and the durability of the product.

Optionally, the cutting line for cutting the flexible membrane 3 coincides with the boundary between the first region B and the second region E or is located in the first region, as shown in FIG. 5 and FIG. 6 shown. That is, there is no laminating adhesive 2 at the cutting place where the flexible film 3 is cut, so that the cutting efficiency can be improved, and thus the production efficiency can be improved.

Optionally, before cutting the flexible film 3, the orthographic projection of the flexible display substrate 1 on the flexible film 3 is located in the flexible film 3, that is, the flexible display substrate 1 and the flexible When the film sheets 3 are bonded, the entire flexible film sheet 3 and the flexible display substrate 1 are affixed on a large board. Compared with the related art, attaching multiple flexible films 3 to the flexible display substrate 1 can effectively reduce the bonding tolerance and improve the product yield.

Some embodiments of the present disclosure also provide a flexible display panel 100, which is manufactured by using the manufacturing method described above.

In the flexible display panel provided by the present disclosure, since there is no laminating adhesive or a part of the laminating adhesive at a position corresponding to the bending area, when the flexible display panel is bent, it can effectively eliminate the problem caused by the flexible display substrate and the flexible film. The squeezing force of the bending on the adhesive leads to wrinkles in the bending area caused by the flow of the adhesive, reducing the risk of breakage of the flexible display panel wiring, improving the reliability of the flexible display panel and the durability of the product. .

The flexible display panel 100 includes a bending area A and a non-bending area C. The laminating adhesive 2 is located in the non-bending area C. There is no laminating adhesive at a position corresponding to the bending area A. At least a part of the position corresponding to the folding area A does not have a bonding adhesive, so when the flexible display panel 100 is bent, the pressing of the bonding adhesive 2 due to the bending between the flexible display substrate 1 and the flexible film 3 can be effectively eliminated. The force causes wrinkles in the bending area caused by the flow of the adhesive, reduces the risk of breakage of the flexible display panel 100, and improves the reliability of the flexible display panel 100 and the durability of the product.

Optionally, the region without the adhesive (ie, the first region B) is slightly larger than the bending region A, and the distance between the boundary line of the adhesive 2 and the boundary line of the bending region A may be 20 -30um, so that when the flexible display panel 100 is bent, the influence of the adhesive 2 on the bending can be completely avoided, and the pressing force on the adhesive 2 due to the bending between the flexible display substrate 1 and the flexible film 3 is eliminated. This results in wrinkles in the bending area A caused by the flow of the adhesive 2, reduces the risk of breakage of the flexible display panel 100, and improves the reliability of the flexible display panel and the durability of the product.

Optionally, the orthographic projection of the flexible film 3 on the flexible display substrate 1 is located in the non-bent area C, that is, the flexible film 3 is not provided in the bent area A, so that when the flexible display panel is bent, The routing of the bending area A can be located on the neutral layer without being affected by force.

Of course, the orthographic projection of the flexible film 3 on the flexible display substrate 1 may also cover a part of the bent area A. Since the portion of the flexible film 2 corresponding to the bending area A has been partially removed, the flexible film 3 outside the bending area A cannot be connected as a whole, so that the bending of the flexible display panel 100 can also be reduced The stress on the traces in area A.

Some embodiments of the present disclosure also provide a display device including the flexible display panel as described above. The display device may be any product or component having a display function, such as a television, a display, a digital photo frame, a mobile phone, and a tablet computer. The display device further includes a flexible circuit board, a printed circuit board, and a back plate.

Step S1: Provide a rigid carrier board 1000, and after preparing the flexible display substrate 1 on the rigid carrier board 1000, peel the flexible display substrate 1 from the rigid carrier board 1000;

Referring to FIG. 2, the rigid substrate 1000 may be a quartz substrate or a glass substrate. A flexible substrate and a display element located on the flexible substrate 1000 can be sequentially prepared on the rigid carrier plate 1000, and the flexible substrate is peeled from the rigid carrier plate 1000 using a laser lift-off technology to obtain a flexible display including the flexible substrate and the display element. The substrate 1 and the flexible substrate may be a polyimide film. The display element includes a driving thin film transistor and a light emitting unit. The light emitting unit includes an anode, a cathode, and an organic light emitting layer. Since the thickness of the flexible display substrate 1 is relatively thin, generally about 30um, the flexible display substrate 1 needs to be attached to the flexible film 3, and the flexible film 3 is used to provide a certain degree of support for the flexible display substrate 1.

Step S2, providing a flexible membrane 3, and applying a laminating adhesive 2 on the flexible membrane 3;

Among them, the flexible film 3 can be PET (polyethylene terephthalate). Of course, the flexible film 3 is not limited to PET, and other organic films with certain flexibility can also be used. The adhesive film 2 is coated on the flexible film sheet 3 in areas, wherein the position corresponding to the first region B of the flexible film sheet 3 is not coated with the adhesive film; the curved region A of the flexible display substrate 1 is on the flexible film sheet 3. The projection of is within the boundary of the first region B of the flexible film 3 or coincides with the first region B of the flexible film 3; or the orthographic projection of the first region B on the flexible display substrate 1 is located on the flexible display substrate 1 Inside the curved area A.

Step S3. As shown in FIGS. 3A-3C, the flexible film 3 and the flexible display substrate 1 are bonded together;

The orthographic projection of the flexible display substrate 1 on the flexible film 3 is located in the flexible film 3, that is, when the flexible display substrate 1 and the flexible film 3 are bonded, the entire flexible film is 3 Large-board attachment with the flexible display substrate 1, as compared with attaching multiple flexible films to the flexible display substrate respectively in the related art, can effectively reduce the bonding tolerance and improve the product yield.

As shown in FIG. 3A, the symmetrical center line of the region B without the adhesive coincides with the symmetrical center line of the bending region A, and the region B without the adhesive may be slightly larger than the bending region A. For example, when the region B with no adhesive is slightly larger than the region A with a bend, the distance D between the boundary line of the region without the adhesive B and the boundary line of the region A may be 20-30um, for example, 25um . As shown in FIG. 3B, the symmetrical centerline of the region B without the adhesive coincides with the symmetrical centerline of the bending region A, and the orthographic projection of the region B without the adhesive on the flexible display substrate 1 and the folded region A Consistent. As shown in FIG. 3C, the symmetrical centerline of the region B without glue is coincident with the symmetrical centerline of the bent region A, and the orthographic projection of the region B without glue on the flexible display substrate 1 is in the bent region A internal.

As shown in FIG. 4, FIG. 4 is a schematic diagram showing a planar distribution of an adhesive-coated region (ie, the second region E) and an adhesive-free region (ie, the first region B). It can be seen that there is a non-adhesive region B in the portion of the flexible film 3 corresponding to the bending area A. After the flexible film 3 and the flexible display substrate 1 are bonded, since the position corresponding to the bending area A is No adhesive is applied, so when the flexible display substrate 1 is bent, it can effectively eliminate the flow of the adhesive 2 due to the squeezing force of the flexible display substrate 1 and the flexible film 3 on the adhesive 2 Wrinkles in the bent area A caused.

When multiple display elements are formed on the flexible display substrate 1, after the attachment is completed, the flexible display substrate 1, the adhesive 2 and the flexible film 3 can also be cut along the cutting line between the display elements to obtain Multiple independent flexible display panels.

Step S4: Remove the portion of the flexible membrane 3 corresponding to the bending area A;

As shown in FIG. 5, before the flexible display panel 100 is bent, it is necessary to remove a portion of the flexible film 3 corresponding to the bending area A. The flexible film 3 can be directly cut by using the laser 4 along the boundary between the coated area E and the unbonded area B, as shown in FIG. 6. After the flexible membrane 3 is cut along the above-mentioned boundary line, the flexible membrane 3 without the adhesive region B is automatically peeled off to complete the partial removal of the flexible membrane 3. Compared with the related laser scanning type burning of the flexible film, the remaining of the flexible film and the impurity particles caused by burning are reduced, and the flexible film 3 in the bending area A can be completely removed, and the laser cutting efficiency is improved at the same time , It is beneficial to improve the production efficiency of display products and reduce the production costs of display products.

The bent flexible display panel 100 is shown in FIG. 7. Through the technical solution of the present disclosure, the bending force between the flexible display substrate 1 and the flexible film 3 can effectively eliminate the pressing force caused by the bonding adhesive 2. Folding of the bending area caused by the flow of the adhesive 2 reduces the risk of breakage of the flexible display panel wiring, and improves the reliability of the flexible display panel and the durability of the product.

In the above embodiment, the cutting line for cutting the flexible film 3 is located at the boundary between the coated area E and the non-adhesive area B. In addition, the cutting line for cutting the flexible film 3 may also be located at the non-adhesive area. In the glue region B, as shown in FIG. 8, the flexible film 3 is cut along a cutting line located in the glue-free region B, as shown in FIG. 9. After the flexible film 3 is cut, a part of the flexible film 3 inside the cutting line in the non-adhesive region B is automatically peeled off, and the flexible film 3 is partially removed. Compared with the related laser scanning type burning of the flexible film, the remaining of the flexible film and the impurity particles caused by burning are reduced, and the flexible film 3 in the bending area A can be completely removed, and the laser cutting efficiency is improved at the same time , It is beneficial to improve the production efficiency of display products and reduce the production costs of display products. The bent flexible display panel is shown in FIG. 10. Through the technical solution of the present disclosure, it is possible to effectively eliminate the sticking caused by the pressing force on the bonding adhesive 2 caused by the bending between the flexible display substrate 1 and the flexible film 3. The folding of the bending area caused by the flow of the glue 2 reduces the risk of breakage of the flexible display panel wiring, and improves the reliability of the flexible display panel bending and the durability of the product.

In the technical solution of the present disclosure, since there is no laminating adhesive 2 or a part of the laminating adhesive 2 in the bending area A, when the flexible display panel 100 is bent, it is possible to effectively eliminate The squeezing force of the bending on the adhesive 2 causes the folding area to fold in the bending area caused by the flow of the adhesive, reducing the risk of fracture of the flexible display panel wiring, improving the reliability of the flexible display panel and the reliability of the product. Durability.
